What's the difference between Pro and Lifetime + BYOK?

Pro ($20/mo, or $192/year) bills you for AI usage on our infra — easiest to start. Lifetime ($129 launch price, later $149) lets you plug in your own API key from OpenAI, Anthropic, Google, etc. — every feature unlocked, you pay your provider directly. Heavy users save hundreds.

Which providers and models can I use with BYOK?

OpenAI (GPT-5, GPT-4o, o4-mini), Anthropic (Claude Opus / Sonnet / Haiku 4.5), Google (Gemini 2.5 Pro / Flash), xAI (Grok 4), Groq, DeepSeek, Mistral, and OpenRouter as a meta-router.

Is my code sent anywhere I should worry about?

Code is sent only to the AI provider you've selected — and on Lifetime, that's your account, not ours. We never log, train on, or store your prompts or your code.

Will it slow down the Apps Script IDE?

No. The extension lazy-loads its panel and only talks to the AI when you ask it to. We've benchmarked < 40ms added to first paint.

Pro is monthly with one-click cancel. Lifetime is a one-time payment with a 30-day refund window.

TESTIMONIALS

What devs (and non-devs) are saying.

I rewrote our entire Workspace automation stack in a weekend. The full-project context is the killer feature — Cursor, but for the one IDE I can't replace.

Aliya B.

Senior Apps Script Engineer · Logistics co.

Lifetime + BYOK was an instant yes. I plug in my Anthropic key, pay $0.40/day in tokens, and get an AI that actually understands `SpreadsheetApp.getActive()`.

Cody P.

Workspace Consultant

Onboarded our 6-person ops team in one stand-up. They went from 'what's a trigger' to shipping internal tools in a week.

Marisol T.

Head of RevOps · SaaS startup

I'm not a developer. I run a bakery. GS Copilot lets me automate my Sheets like I have an engineer on staff.

Renee D.

Owner · Sourdough & Co.

I used to spend hours debugging script errors. Now I paste the error message and get the fix in seconds. It's like having a senior dev on call.
